Yep, I've done various ways of running WoW, including RAID0 300GB Velociraptors, RAID0 36GB Raptors, RAID0 320GB 7200rpm, and an SSD. The key is the access time. An SSD can locate a file in 0.1-0.3ms, while the fastest Velociraptor is around 4.10ms. That's a huge difference when you're trying to locate hundreds of files on a drive. Just think of every piece of gear on every player in your local area when you visit a battleground or Dalaran - every piece of gear has textures and animations that have to be loaded. When you enter an area with 200 players, and each player has roughly 50 textures to load.. that's a sudden request for 10,000 files from your hard drive. These data files needed to be transferred aren't very large (evidenced by the comparatively ugly and pixellated textures), so the transfer rate doesn't matter at all as much as the access (seek) time.
My next step will be hosting WoW from Acard's ram drive with 16-32GB of memory.. which supports RAID0 from one Acard box. I'm positive this will be faster than any hard drive option short of a true main memory ram drive, but I don't want to take 12GB of space away from system memory to dedicate towards WoW, nor do I want to have to rebuild the ram drive after every reboot. Acard's unit has a battery backup - system ram drives don't.
